Product details
Overview
ES1HL from Taiwan Semiconductor is a 1A, 600V super fast surface-mount rectifier in Sub SMA package, featuring 1.70V max forward voltage at 1A and 35ns reverse recovery time, used for freewheeling and switching-mode DC-DC converters.
For engineers reviewing the ES1HL datasheet, ES1HL pinout, ES1HL application, or ES1HL equivalent, key selection criteria include peak reverse voltage rating, forward voltage drop under load, thermal resistance (RθJL = 35°C/W), and moisture sensitivity level (MSL 1).
Technical Context
The ES1HL is a single-die, glass-passivated silicon junction rectifier optimized for high-frequency switching applications. Its 600V VRRM, 30A IFSM, and 35ns trr enable efficient operation in compact power supplies where fast turn-off and low conduction loss are critical.
Designed with matte tin-plated leads compliant with J-STD-002 and JESD 201 Class 2 whisker testing, the ES1HL supports automated SMT assembly and operates across –55°C to +150°C junction temperature range with UL 94V-0 molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage before breakdown; defines safe operating limit in high-voltage DC-DC stages |
| IF | 1 A - continuous forward current rating; determines steady-state power handling capability |
| VF (max) | 1.70 V @ 1A, 25°C - forward voltage drop directly impacts conduction loss and thermal design |
| trr | 35 ns - reverse recovery time; enables stable operation up to ~10 MHz switching frequencies |
| RθJL | 35 °C/W - junction-to-lead thermal resistance; supports direct PCB copper pad heat sinking without heatsink |
| IFSM | 30 A - non-repetitive surge current rating; withstands inrush and transient overloads in SMPS startup |
| CJ | 8 pF @ 1 MHz, 4 V - low junction capacitance minimizes switching noise and EMI in high-speed topologies |
Pinout & Package
Package: Sub SMA - low-profile, surface-mount plastic package with cathode band marking; dimensions per TSC package outline drawing; MSL Level 1, RoHS and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current input | Connected to source-side of switching node; requires adequate copper area for thermal dissipation |
| Cathode | Forward current output / reverse voltage terminal | Marked by band; connects to output rail or ground return path; polarity-critical for correct rectification |
Key Features

| 35 ns reverse recovery | Reduces switching losses and ringing in 100–500 kHz flyback and forward converters |
Applications
| DC-DC Converter Secondary Side | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Output rectification in isolated 12V/24V buck-derived DC-DC modules for industrial PLCs. IC Role / Device Role / Timing Role: High-efficiency synchronous rectifier replacement; handles 1A continuous output current with minimal voltage drop. Use Value: 1.70V VF reduces conduction loss by ~12% vs. standard FR107, improving full-load efficiency by 0.8–1.2%. | Use Scenario: Freewheeling path in half-bridge motor drive inverters for HVAC blowers. IC Role / Device Role / Timing Role: Fast-recovery clamp diode across inductive load; suppresses voltage spikes during MOSFET turn-off. Use Value: 35ns trr limits voltage overshoot to <15% of bus voltage, eliminating need for snubbers in 200 kHz designs. |
| AC-DC Adapter Output Stage | Telecom Power Supply OR-ing |
Use Scenario: Secondary-side rectification in 5–12W wall adapters for IoT gateways. IC Role / Device Role / Timing Role: Primary output rectifier in discontinuous conduction mode (DCM) flyback topology.

IC Role / Device Role / Timing Role: Unidirectional current path enabling hot-swap redundancy without backfeed. Use Value: 600V VRRM provides 2× safety margin over 48V nominal; 35°C/W RθJL allows direct pad mounting on 2 oz copper. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay ES1J | Same 600V VRRM, 1A IF, but VF = 1.7V typ (not max); trr = 35ns; Sub SMA package | Identical mechanical fit and electrical envelope; minor VF distribution shift affects thermal margin in high-ambient designs | Select ES1HL when guaranteed max VF ≤ 1.70V is required for worst-case thermal validation |
| ON Semiconductor MUR160 | 600V VRRM, 1A IF, but DO-41 through-hole; VF = 1.7V max; trr = 50ns; RθJA = 100°C/W | Requires PCB redesign (through-hole vs. SMT); higher trr increases switching loss; inferior thermal performance | Choose only if legacy through-hole assembly is mandated and layout change is not feasible |
Compared with Vishay ES1J and ON Semi MUR160, the ES1HL offers tighter VF max specification and superior thermal resistance in an MSL 1-compliant SMT package-critical for high-density, thermally constrained power modules.

FAQ
What is the maximum forward voltage drop of the ES1HL at rated current?
The ES1HL has a maximum forward voltage (VF) of 1.70 V at 1 A forward current and 25°C junction temperature, as specified in the Electrical Specifications table. This value is guaranteed across production lots and forms the basis for worst-case conduction loss calculation in the ES1HL design-in process.
Does the ES1HL support lead-free reflow soldering?
Yes, the ES1HL features matte tin-plated leads qualified per J-STD-002 for solderability and complies with lead-free reflow profiles (peak temperature ≤ 260°C). Its MSL Level 1 rating means it can be stored indefinitely before assembly without baking.
What is the reverse recovery time specification for the ES1HL?
The ES1HL has a maximum reverse recovery time (trr) of 35 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications section and applies to all ES1HL units regardless of date code or wafer lot.
Is the ES1HL pin-compatible with other devices in the ES1xL series?
No-the ES1HL shares the same Sub SMA package and two-terminal configuration with all ES1xL variants, but its electrical ratings (especially VRRM = 600 V and VF = 1.70 V max) are unique to the 'HL' suffix. Pinout is identical across the family, but substitution requires verification of voltage and thermal requirements.
What does the 'L' suffix in ES1HL indicate?
The 'L' suffix in ES1HL denotes Taiwan Semiconductor's low-profile Sub SMA package variant, distinguishing it from standard SMA or DO-41 versions. It confirms compliance with MSL Level 1, RoHS, and halogen-free standards per IEC 61249-2-21, as documented in the Mechanical Data section.
